		<description><![CDATA[There are some times where using static routing on firewalls is simply not scalable&#8230; As long as the routing is inside a trusted network, I do not see any reason to avoid dynamic routing. Juniper devices (Junos and ScreenOS) can even use virtual routers to split the routing domain into several domains. In the example [...]]]></description>

		<description><![CDATA[Load-balancers like ACE are used &#8211; as their name says &#8211; to balance traffic among several servers able to serve the same content. The easiest case is to load-balance web static content. In that particular case, when a client get a page composed of several objects (e.g. style sheets, images) it does not really matter [...]]]></description>

		<description><![CDATA[Nowadays, having a load-balancer in datacenters is more and more crucial not only to assure an easy scalability but also to assure high availability (HA). If properly configured, the load-balancer will be able to detect a failed application server, will remove it from its resource pool and will eventually reassign clients to other available servers.
